解剖型股骨球头

BIOLOX CONTOURA

BIOLOX®delta陶瓷制成的新一代软组织友好的大直径解剖型股骨球头.

在髋关节置换中,采用大直径股骨头假体用来降低脱位风险,脱位是导致失败的主要原因。据报道,初次置换脱位发生率在0.5%到5.8%之间,翻修手术为4.8%到13%。许多大型系列研究结果显示:增加股骨头直径可减少脱位风险1。大量临床研究显示增加股骨头直径可以降低髋关节脱位风险2

最新设计的BIOLOX CONTOURA股骨球头减少了与髋关节前侧软组织接触区域体积。大直径股骨球头BIOLOX CONTOURA在有效降低脱位风险的同时表现出良好的软组织友好的特点3,4

最近的研究结果显示普通球头边缘可撞击周围软组织,特别是髂腰肌,从而导致髋关节前侧痛活动受限5–15
